angiyou'll find reviewsme, on home repair to healthcareon. written by people just like you. you want to be sure the money you're about to spend is money well spent. angie's list -- reviews you can trust. we need help up from the medical tent. get as many people up here as you can from the medical tent. >> they were banged up bad. severe lacerations, amputees, a lot of shrapnel. pretty big explosion. >> this cowardly act will not be

taken in stride. we will turn every rock over to find the people who are responsible for this. >> we see there the images that are moving the countries. good morning to all cnn viewe , viewers,iam chris cuomo in boston. we welcome all of you in the u.s. and around the world. can you see what i am holding in front of me? this is "the boston herald." the picture always tells 1,000 words. people here to celebrate, people here for patriots day, a cultural fascination that brings families together from here and 100 different countries turned into chaos, two different explosions. two different bombs. today, the struggles, they continue. the story notary for the over 150 people who were injured, the

three people and their families who lost their lives in the hospital right now, people continuing their battle for their lives. many still seriously and critically injured. we'll give you the latest on them and their stories are developing. also, here is what we know at this hour about the investigation. of course, two tracks going on. among those who lost their lives. one picture stayed with us this morning. an 8-year-old boy. his name, "the boston globe" says, martin richard. you are looking at him there. a picture so many can identify with, because you have a kid like him. you have a picture of a commune, holding up his name. made by his parents or god parents. the story of how he lost his life, equally heart wrenching. here with his sister and his mother. here to cheer on his daddy, running the race. they gathered on the sidewalk to give him that celebratory hug that so many families were here for, he loses his life.

his sister loses her leg. his mother has a brain injury, is in the hospital as we speak. that father loses in one way or another, everything that mattered to him. his life, families like him, dealing with this type of loss and pain. in the hospital still, at least 17 people in critical condition. the medical response here, a huge part of the story. the injuries that we saw yesterday, that we did not show you, looked like a war zone. this bomb, improvised explosive device type of explosion. the power, devastation, but on scene, people here to help with the marathon. to help with cramps and maybe cardiac arrests, became emergency traumatic triage, saved lives yesterday. who did it? that's the second wroprong of t story. the investigation.

no group has claimed responsibility. what does that mean to investigators? on all levels, they are scrambling, joint terrorism and task force on the ground. vehicles and personnel from so many different agencies, canvassing all night long. there was an excuted search at an apartment, has not been named a suspect. authorities are interviewing him. this goes from the fbi, top down, the white house, washington meeting about this the president making statements, making sure all resources on the ground to see who did this and why. we know the investigators have leeds. we know that they feel positive about the progress they are making. and we are covering it from all angles, extensive team coverage of this developing story. again two tracks. what do we know who who did this and why?

a lot of that has to do with the bomb, the signature, the materials, how they could have been accessed. how it was made, what it tells us about the level of sophistication. what is on our heads and hearts this morning are the people who were hurt here, the people who lost their lives. poppy harlow, at one of the hospitals still fighting battles for the wounded. susan candiotti, latest on the investigation for us. briana keilar, at the white house with the latest response for how they are moving assets and information. and then what is the reaction to this story here in boston? the larger home of the country? the world and its markets? alison kosik at the wall street center to figure out what's going on, looking into markets with us. of course, again, as i've said many times, because it bears repeating. the most important part of this story, those who were injured, over 150, those who lost lives, three people luckily so far that number has not moved up.

hopefully it doesn't. let's go to carol costello, on the set. she has more on the little boy whose life was taken here yesterday. >> we talked a lot about martin richard, chris. that little boy. sadly, the face of this tragedy. just eight years old, a much loved boy. a picture of martin according to affiliate station whgh, ran into the street to hug his dad, just about to finish the race. that tragically killed him. martin's 6-year-old sister lost her leg and their mother suffered a severe brain injury. at their home in dorchester, suburb of boston, candles burn, and the world peace scrawled on the sidewalk outside the house. martin's relatives are greeting. his cousin tweeted. i love you, martin. you will be in my mind forever and forever. martin, you were the sweetest, funniest boy.

i'm going to miss you so much, are you an angel. said his aunt. his little sister, in the hospital, we believe she lost her leg. his mother is out of surgery. we assume the father is okay, at least physically. the richards family deeply involved in all facets of life in dorchester from little league and soccer to their church. the prayers, online everywhere, people tweeting prayers for the family who has lost so much. >> carol, thank you so much. they are needed. the little boy, looks so perfect. but such a sign of how he was just beginning his life. so hard for this family to recover, and families like them. maybe they didn't lose somebody,

but they have somebody injured. maybe they don't have somebody in the family, but they knew someone. so many layers of injury and hurt going on here. remember, it is not over. many still in the hospital. they face critical injuries. like the loss of their limbs. pictures that we saw that we are not showing you, really speak so loudly that this could have been worse. poppy harlow at one of the hospitals, continuing team coverage at brigham & women's hospital right now. poppy, what do we know about the current status of people still in the hospital, what needs to be done? >> good morning, chris. i'm so glad you brought up the point that this is really just the beginning, that some of these patients that have the most severe, most complex injuries, that had to have amputations will have to come back again and again for repeat surgeries. what we heard from one of the

trauma surgeons at mass general. bad news for viewers. number of injured has increased by ten. 154 people, that is cnn's latest count, according to all of the hospitals here in the area that we have spoken to. 154. behind me here at brigham & women's, treating the most injured of all of the hospitals, 31. i can tell you the number of critically injured remains at 17 where it's been at the middle of the night. those seriously injured has risen from 25 to 41. 10 people have lost a limb in this attack through amputation. the only slight improvement i can share with viewers on injuries, chris, comes to children. and as we follow what carol just told bus that beautiful 8-year-old boy who lost his life, we know that nine children were injured in the attack.

eight of them we were told were treated at boston children's hospital. i just got off the phone with boston children's hospital, their spokeswoman and she told me of the eight children that they treated, none are or were in critical condition, that their conditions range from good to serious. that some were treated and actually released overnight. we doan know how many. we do know that all eight children are not still at the hospital, and that is a bright sign. of course, we'll keep in touch with them to find out the status of the rest of the children. but that is the only improvement, when you look at the bigger picture, number of casualties -- excuse me, the number of injuries has gone up by ten. all right. poppy, thank you very much and you are right. we take good news where we can find it. we'll keep coming back to you. we want as much information about people hopefully getting out of the hospital and getting on with healing and their

families back to their lives. two tracks, remember, what is going on with those affected by this on the ground and then the investigation to find out who did this and why. authorities are still looking for clues behind the deadly attack. federal and local authorities are right now searching a home in nearby revere, not right now, did it last night. we believe it was done with the cooperation of an individual who is in the hospital. not named as a suspect or person of interest, but what does that mean? it means they are cooperating, that there was a level of access. they went in, left with a bag of evidence. we are told the apartment is linked tie young saudi man in the u.s. on a student visa not named a suspect, a person of interest. could be informational. casting a very wide net. we hear nothing has been found related to the bombings, very important. in the interest of what happened, we don't want to overinclude people or theories

that do not deserve it at this point. the investigation, the fbi leading it. the joint terrorism task force. the best coordinated set of agencies that we have to deal with homeland security. cities around the country on higher alert because of this. big cities, cities with sporting events playing attention to this. we'll learn from it. do things differently. what does it mean in terms of how the investigation moves forward? from what they learn on the phone, very sophisticated. cnn national security analyst, former assistant for homeland security, fran townsend. thank you for joining us this morning as part of our team coverage. any new information for us from your sources? >> i do, chris. talking to federal law enforcement officials, i understand the fbi's emergency response team this is the team that goes to the crime scene, collects all of the evidence, referred to as the ert. they have cleared the crime

scene. it doesn't mean it's open. you see the boston pd is still there. the fbi's emergency response team has collected evidence at the crime scene, finish line of the boston marathon and inventorying it, they will look at it and use it to help them prioritize interviews and how they go through, what order, video surveillance camera tapes to identify and link them to the evidence found in at the scene. we also understand from federal investigators that they have not found -- reports early on of ball bearings being used to -- as part of these devices to increase the injuries. federal investigators tell me they have not found ball bearings, but their current theory they are working on, these devices were placed in trash cans and when the trash cans exploded that would have made the shrapnel that caused all of these horrific injuries that poppy was talking about. next, they tell me we know there were two bombs at the finish

line at the boston marathon. we heard reports there could have been as many as two, possibly three, unexploded devices that were seized. federal investigators tell me, look, there were lots of unattended packages destroyed. that may be what those reports were referring to. but right now, federal investigators believe there were only two bombs that were exploded and caused all the damage at the end of the boston marathon. and finally, chris, you reported about this saudi student. i understand from federal investigators this individual has been very cooperative. not a suspect. and right now they don't believe they have anything of significance out of that search. >> all right. thank you very much. fran, appreciate it. we'll come back to you when you get more information. keep the story moving forward. thank you very much. a number of factors, size of the area, number of people, look at these two ways. there is tons of access and a

needle in a haystack, so many different people and variables. cnn analyst, former assistant homeland security juliette kayyem joining us. let's pick up something fran said there. when you look at this, how does this rate as a difficulty factor for an investigation? tons of people? cell phone communication, closed circuit tv, everybody has a device these days, lots of eyeballs on the situation, and yet also so much to go through. how do you balance it? >> overall, it's going to be pretty good for the investigation for the reasons you said. this was a high-profile event, lots of cameras, potentially eyewitnesss, we'll have to cull through that, see who knew what, saw what, maybe didn't know they saw something. up somebody came in. you have the cameras and the bomb material. >> following up with the cell phone information, it tells us who was talking to whom, but may relate to detonation? >> potential detonation.

at the two moments of detonation, you might link it to a service and then the service might link it to a potential customer. one can only assume. we don't know if a cell phone was being used. i will say this. they almost immediately moved to stop the runners, half a mile. move them from boylston to commonwealth street. i saw them walking down the street yesterday. the key thing you have to do for the investigation, you secured the crime scene so it wasn't chaotic there. once they got the initial people out it did preserve a sort of area where the fbi and others are in there looking at the forensic evidence. that is key and that was a really smart move, in their mind, they had, wait this is clearly a crime scene, we can't have thousands of people mulling through. >> and also mitigation, right? two explosions, 12 seconds apart, how much more could it have been? thousands of innocents running up, exhausted, mentally drained.

very vulnerable. >> you have no idea where you were. there were family reunification issues, i talked to people who were looking for their families. those are now fine. the city bouncing back. noisy now, getting later in the day. part of that is liked to how good the response was. not panic, not kay ottic. we think of resiliency as a mood. not just a mood. it's related to how the response occurred. we might go, oh, how could this happen? failure of intelligence? really a sign of a very resilient nation is one that can respond quickly and get people back on the streets. i just saw a bunch of runners, that's good. and a much lighter note here obviously, seriousness. so many people didn't get to narn race. it will sbe interesting to see what the city does to move forward. >> there will be a marathon next year. >> i'm sure, and different and

hopefully better than any other before because of what they learn and how they come together here. juliette, thank you very much. we piece this together, so much to this story, as it continues to develop. we'll track the investigation and we'll be tracking the latest on the people still fighting for their health and well-being in the hospital. when we come back.

>> the opening bell there, business resumes, men and women on the floor, know all too well who it is like to have your life disturbed and in many cases destroyed by violence. that's exactly what happened here in boston as bombs went off, right near the finish line, one of the most beautiful american events, a cultural collaboration, in boston. the boston marathon. many runners just steps away from completing an epic journey, the bombs placed as we know at

one of the busiest corners, one of the busiest times of the race, someone able to finish before this happens, one of the lucky ones, denoted by the coveted yellow jersey, julie jesse of north dakota. julie, congratulations on finishing the race. >> thank you. >> thank god you got through before this all happened. from north dakota, showing how huge this is. 100 countries, almost every state represented. you finished. where were you, what was going on? >> finished about ten minutes prior to the blast. i got my heat blanket, my medal and i had just gotten my food, i had to stop for a minute, because my leg was starting to cramp and i was holding on to two gentlemen, and then all of a sudden, i heard a loud boom, everyone's head turned, and by the time we turned our heads, you could see the smoke billowing above the building. >> what did your head tell you what it is?

>> another gentleman was standing there, and i said what do you think that was? and he solidified what everyone was thinking, i think it was a bomb. >> one of the things that kept casualties low was poise and calm. so out of place, such a beautiful event, so unexpected, that people didn't panic right away? >> we really didn't. the gentleman who had told me it's probably a bomb, he said grab yourself, we need to get out of here, so we all kind of just proceeded to the buses to grab our stuff. when i got to the busline, there weren't a lot of people in line at this point. within two to three minutes, a lot of people lined up waiting to get bags. i felt bad for people in the buses, they were getting a little flustered. one of the women next to me, they kept finding the bag and she kept saying my husband and child are at the finish line. i said don't worry, i have a cell phone. we weren't able to reach them. >> people become family in a

moment. in an instant. did you see a lot of that? people doing what they could, even if they were tired from the race, to help? >> you make fast friends. this woman, like i said. i couldn't help her with my cell phone. i gave her a hug, i know your family is going to be fine. i had her husband's cell phone number, we tried to reach him. last night i sent her a text and said i have been praying for your family. i hope they are safe. the safety has been weighing on my mind. and she texted me back, said they were just fine. >> were you close enough to see how people were affected? >> u.at that moment, everyone w having a hard time processing it. let's get our stuff, get out of here. we need to be away from this. >> making the right choice. deal with it two ways. the worst marathon or the o--

>> this is my fourth marathon. watching the volunteers and the spectators, i would come back and volunteer, just this tribute. >> that's what matters most. >> thank you. thank you very much. glad your family is okay. >> thank you very much. >> juicy jeske, able to firn. thousands did not. part of the living legacy of this race. how the city decides to come back from all of this. we too will come back after a break. there is more and developing information about this investigation. the fights going on in hospital for people to keep their lives intact. we'll give you it all when we come back.

welcome to cnn's continuing team coverage of the boston marathon bombings. i'm chris cuomo here in boston. the investigation continues all

around us. any moment, the fbi will hold a news conference on the bombings that occurred. we'll bring that to you live. we're hoping learn more at that press conference. it will involve the police, governor, and the fbi. we do know overnight, the search of an apartment in a nearby town in reveer, connected to an interview going on at a hospital. with somebody at an event. we hear they are cooperating, a search, a bag of evidence taken out. bomb technicians took part no discussion of any possible link to the bombings, very important to remember. want the investigation to move forward, but accurately and correctly. and an 8-year-old boy has been stealing our hearts this morning. one of three people who lost their lives. "the boston globe" says his name is martin richard.

the photo you see, the beautiful boy, his commune, his white little suit, there he is. perfect in every way. and then his life was taken. he was here to see his daddy, running the marathon. his mother and his sister were here as well. both seriously wounded. both in hospital as we understand. one family that suffered such tremendous loss. so many others dealing with loss as well. 15 4 wounded, and remember, just because you don't lose a life doesn't mean you get away for free. people have very serious injuries, dismemberments, amputations later at the hospital. grave internal injuries. so much that was done here at the scene, prevented further loss of life. finding out what was going on in the hospital. trying to get the latest on what they get released.

good news where we can find it, also the investigation. what's going on here on the ground? latest searches. this is a massive, coordinated effort run by the fbi. the joint terrorism task force. our team coverage, focusing on this as well. national correspondent susan cann candiotti, when you look at this, you have been following it all night. when we look at the intensity. >> it ranks right up there, chris, going back to the 9/11 bombings, going back to the oklahoma city bombing and coming up on that anniversary, this week, as a matter of fact. all of the terrorist investigations bringing in assets as you said from different agencies. >> from the city of boston, the

pd, all the federal investigations. and right now we're looking at what is a domestic attack. they just don't know. they are at the beginning stages. as our cnn national security analyst just told us, we are concentrating on the evidence they picked up so far. the task force, called the federal emergency response team, done collecting all it's going to collect at the crime scene itself, others may be doing other work at the crime scene as well. but they are now concentrating mainly on these devices to try to learn more about them, because if they learn more about them, chris, of course, they may be able to determine and trace who built these things. so they are looking at, for example, certain signatures on these bombs, as fran told us, there are no longer saying they

found ball baerearings. a better explanation seems to be they found a lot of shrapnel. they are the wounds we have seen in many victims. the bomb may have been placed next to another item that created all kinds of shavings that would have been metal, for example, shavings that created so many wounds in so many people. we are looking of course at surveillance videos and hotels and commercial buildings and store around the site of the blast. we want to also mention that at first we were told there were at least one, possibly two unexploded devices, now fran is telling us, that's not the case. when, in fact, they did find other devices, none of them -- other suspicious packages blown out just on the side of being precautious. cautious about these things.

let's catch you up again on what happened in revere. we know of no other place that they conducted a search on, officials tell me this is the only location that has been searched so far, and it's done without a search warrant. in other words, the auto apartment whom it belonged said it's okay. belonged to a young saudi student 20 years old. that person not regarded as a suspect, they wanted to check everything out. this young man injured in the blast. had a leg injury, and he remains in the hospital. still under guard, he is not considered a suspect. one other saudi national, a woman, also injured, not considered a suspect. a lot of different areas they are looking into, chris. and hopefully we'll be getting more on these devices. that could really help trace

where these devices came from. chris. >> all right, susan. thank you. we'll be checking in back with you. a bomb tech told me it's good news we found devices that turn out not to be bombeds. the problem, when we're not finding the devices, they could be dangerous. what a bomb is made of and how it's made, tell a story of what kind of materials there were, what it would take to access them. limiting the pool of people who could have done it. narrowing, focusing in on what they are looking for. as well aztec neegs techniques. every bomb tells a story. we're waiting for the press conference that will have we are now awe waiting a conference. and boston is learning to

recover as the investigation moves on. rest of the world is reacting to this. one of the major places we see reaction is in the markets. let's go to the new york stock exchange. investigators are beginning a new day of trading. question is, how are they going to see this? are they going to bounce back? are they going to look at this as a continuation of some of the worst losses of the year after yesterday's trading in boston? alison kosik joins us from there. allison, they have north korea, they have gold, the bombings, a lot of negative energy if they want to feed off of it. what do you think? >> at this point, stocks rebounding, down 96 points. before the bell rang, there was a moment of silence to honor the victims of the bombing in boston. a sign of solidarity and support. and the new york stock exchange did this after newtown.

it always happens before 9:30, the idea is to not disrupt trading, in an event like what happened in boston happens, you really want to see the markets function normally. you do see a rebound happen, triple digit sell-off yesterday. there was some upbeat economic news that come out giving the markets a boost. housing markets continue to show it's recovering. inflation report came out, showing inflation is tame. and we're seeing markets overseas recovering too. that's good news as well. wall street at this point, the way it sees it, the bombings really didn't grow into a much worse situation. part of the reason you saw that sell-off yesterday, it was that uncertainty. is this going to grow? the only city where this will happen? investors certainly had that knee jerk reaction, sold off, now they are buying back into the market today. once again, dow up now 118 points, the focus today, chris, is going to return to the economy and company news.

company earnings continue to come out. i think their hearts, chris will, remain in boston. chris. >> yeah, we hope so. that's the focus today. good to see wall street take a positive look on events. moving things forward. they are reacting, remotely to what people lived through here in boston. i'm joined by cassidy. good to meet you. glad you are safe. you were there yesterday, watching, when the explosions go off, where are you? what does it mean? >> about 30 feet from the firn line when explosions went off. didn't know how to react. the first explosion, i felt it first and heard it at the same time. my legs were changing. and then before i even had time to internalize, and react, the second one happened and then everyone started running inside. i tried to hide in the atm machine area nearby. try to figure out what to do next, figure out what was going on? it was terrifying?

>> you had a camera on me. >> i had a dslr, my phone camera, hd camera, i'm a video blogger. i'm alive, there are a lot less people who are less fortunate so if i'm here, might as well try to show people in other places what is going on, post video as quickly as i can. you can't understand it unless are you actually there. >> what is the look through your lens? what kinds of things did you see? >> walking, taking video, i walked past a restaurant on newbur street i thought was giving out pitchers to water. and there was actually a person bleeding on the street there, right off the sidewalk, just laying down and luckily the restaurant was helping them. great to actually see people teaming up together to help people in need. everyone around me, no one knew what to do. and i captured this utter chaos. >> did you see the triage going on? help runners with what usual happens after a race?

turn into a trauma scene? >> some people were running away, even people who were volunteers, police, just regular passer byes standsing to watch the race, teaming up and working together to help take down the finish line, and tear down fences, get rid of something so cars and ambulances could come through. >> seeing such an unnatural thing, people hurt that way, how did you keep it together? >> i doan know. honestly, i got home last night at about 11:00, and started to break down. i had been holding it in all day, trying to remain composed and social media and on video, try to portray what was happening, tell people what is going on, tell my story, by the time i was trying to fall asleep, it was all hitting me, this is really real. waking this up morning and realizing it's not a nightmare, it actually happened and what is going to be the case today. >> good news it's over, now we figure out how to move forward. cassidy, thank you so much for being with us.

we will turn our attention to the press conference going on in boston. authorities are expected to update the investigation, we are expecting to hear from the fbi special agent in charge, and possibly boston police commissioner and the governor. let's tune in to the press conference. >> organize a briefing for you with the information we have the mayor is here, members of the congressional delegation. all of the law enforcement leadership, several people who want to present to you this morning and take your questions. a couple points i want to mention at the outset. i told you yesterday that the fbi has taken charge of the investigation, special agent in charge rick will speak shortly. it's important to clarify that two and only two explosive devices were found yesterday. other parcels -- all other

parcels in the area of the blast have been examined. no unexploded bombs. no unexploded explosive devices found. over 150 people were injured yesterday. in the -- in the blast. some gravely. our thoughts go out to all of those injured and killed. and to their families and friends. i personally want to thank the extraordinary first responders for their just extraordinary work yesterday. every single one of them, those who were on site and got to the site promptly thereafter performed dutifully as have area hospitals. i have been calling heads of the area hospitals personally to thank them as well. tomorrow, we will organize an interfaith prayer service to help our community heal. no details on that yet, but we will provide those detail when we have them. there is a support center that was opened yesterday and what we

call the castle, opposite the park plaza hotel on arlington and stewart street i think it is. the mayor and his -- has provided stats to help people cope with -- with this extraordinary event and it will be open from 9:00 until 5:00 or beyond this evening. finally, everyone should expect continued heightened police presence and everyone should continue personally to be vigilant. the investigation continues and until it is done, all of those in law enforcement represented by the leaders here will be present in force in the area around the blast and through out the city. let me turn it over to mayor menino. >> thank you, governor. yesterday, terror was brought to the city of boston. tragedy was brought to one of our neighborhoods also.

this is a close-knit place. we know our neighbors, we grieve a little boy we know from dorchester. but also today, i want to say we know our heroes also. they are the men and women who wear helmets, the badges, the runners who helped us yesterday during this time of need. as we go together on this issue with all of the law enforcement officials, we'll make sure the city pulls together. now, we got it under control. let's continue to work together. let's keep offering our helping hands to individual who's may need it during this very difficult time in our city's history. i just say to all of you, mayor for 20 years now, i have never seen law enforcement pull together, working together to solve our crime and our city as they have, but also to help people pull together. the business community, neighbors, everyone. this is a tragedy, boston is a strong city. city that will get through this, and the governor said, we set up a resource center, over at the

castle, and near the park plaza hotel. staff will be available to give information to individuals who are involved in the marathon. open from 9:00 to 5:00, and a phone number is we think our phone number 635-5040 i believe and our hotline -- wrong number. 617-534-5050. and also the 24-hour hotline you need information also. that number 617-635-4500. the last several hours, we receive calls from all over the world, asking information about the tragedy. how they can help us. this is a bad day for boston, and i think if we pull together, we'll get through it, a strong city, and a lot of people willing to work together to make it better for all of our people. as we gather today with all of our officials, let's say boston will overcome. >> thank you, mr. mayor.

>> thank you. >> thank you, governor, thank you, mr. mayor. the president of the united states has pledged his full support in all efforts to keep the city safe and to find the person who did this and bring them to justice. we did not have to reach out to the president. the president reached out to us. he called the governor, called the mayor, called the members of the delegation, because the president is actively involved here and responding. on behalf of our congressional delegation, senator cowen is here with me, and congressman lynch and all of the members of our delegation. we want to extend our thanks to the first responders, to firefighters, to police officers, to ems, everyone on the scene, including the volunteers who came and helped those in trouble and helped save lives. we also want to thank those from all around the country and all around the world whose prayers

and thoughts and offers of help have poured in. we are deeply grateful. as the mayor says, boston will survive. >> thank you. i would like to thank first responders and the volunteer physicians, nurses, and medical staff who volunteered at the marathon. their services and heroic actions saved lives yesterday afternoon. we continue to work shoulder to shoulder with partners at boston police department, massachusetts state police and all other jttf agencies. our mission is clear. to bring to justice those responsible for the marathon bombing. the american public wants answers, the citizens of the city wants answers, and boston deserves answers. the men and women before you

today pledge to do everything possible to get those answers. this remains an active investigation. ongoing investigation in various locations throughout the area goes on. however, there are no known additional threats. we continue to interview various witnesses and process the crime scene. which could take some time. the citizens of massachusetts and the city of boston should expect to see the fbi and jttf partners conducting investigative activity in the greater boston area. assistance from the public remains critical in establishing a timeline of events which leads to swift conclusion through due diligence and strong investigative activity. we commend the public, the citizens of boston and the citizens of commonwealth of massachusetts for information provided to law enforcement so far and strongly encourage assistance to continue. there is paramount to explain the fbi and jttf role to a greater extent.

volume of tips we received, we have received voluminous tips over the last 18 hours since the incident. we have staffed our 1-800-call-fbi tipline and contact that line with additional tips. bringing additional victims assistance and response resources from field offices to boston and they are on site, working as we speak, processing evidence at the crime scene. to the extent that the crime scene in the copley perimeter continues to be a crime scene it may be that for several days. we are following up on a variety of leads. you will see us in law enforcement interviewing the coworkers, your neighbors, and maybe even yourself in coming days. we ask you to consider to cooperate. we hope swift action will yield quick results if that does not diminish our diligence and persistence in combing through the high volume of evidence and

leads we are processing right now. we are just beginning on that path. thank you very much. >> i'm gene marquez, acting special agent in charge. atf, boston field division. at this time, atf has done a partial nrt, national response team activation. we're bringing our explosive specialists here to the team and we'll be working jointly with the atf with its partners on the jttf. we have certified explosives specialives, explosives enforcement officers, special agent bomb techs and canines that are trained. at this time, we have approximately 30 forensics specialists on the scene and to dispel any rumors, there were rumors floating around there were up to seven devices at one time, that is not true. i think that happened as a

result of some suspect packages that were disrupted. but we only have two devices that we're aware of and both of those devices were the ones that did the damage and involved in the explosions. at this time, we are looking for the public's cooperation. we're looking for any video, photographic evidence, if you can please contact the fbi hotline or the city's hotline, we'd like to review any kind of media that you have out there that might give us additional investigative leads. we are pursuing those leads at this time. the scene is going to take several days to process. we just ask for your patience as we're working in that area and for your cooperation. >> good morning. i'm united states attorney carmen ortiz. first i want to extend my condolences to the families of

the loved ones who were lost in yesterday's attack on the city of boston as well as those that were hurt and may still be fighting for their lives. our thoughts and prayers go out to them. what happened yesterday was a terrible tragedy, yet it was amazing to see, as you have heard from my colleagues here, how people just helped one another, ran toward the blast just to assist another person in greater need. people who were just there for those that were hurt and in a dire situation. it was amazing to see how the city of boston and people from around the world that were part of yesterday's boston marathon help one another, console each other. there are so many move williing to an investigation such as this. i can't begin to thank everyone who has been involved, law enforcement, medical

professionals, emergency responders and really just regular citizens who became heroes yesterday. i want to repeat, as i stated yesterday, that this is an active and ongoing investigation. but rest assured that we are bringing all of the necessary resources to assist in this matter and that we will conduct all that we can with all of our law enforcement partners. i've been in touch with the attorney general several times, eric holder, and he has pledged all the resources from the department and others on behalf of the federal government to help boston recover from yesterday. i ask for your patience and your understanding as we continue to pursue leads together, evidence, and to get to the bottom of who did this and why. thank you. >> good morning, my name is ed davis, police commissioner for the city of boston. we are in the process of

securing and processing the most complex crime scene that we've dealt with if the history of our department. we are doing that under the direction of the fbi and in partnership with the atf. we've secured the perimeter with members of the national guard and the general is here. i want to thank the people working closely with us. we received offers of assistance from chicago, los angeles, units have responded from new york city and baltimore and we are working very closely with all of our partners on this complex investigation. i want to stress that the area around the crime scene, which yesterday was 15 blocks, has been reduced to about 12 blocks at this point in time. and we will continue to collapse that crime scene as the facts and circumstances make that available. we want to open up as many streets and get people into their buildings as quickly as we can. we're working diligently on that. but please be patient with us in the time that we need to process

the crime scene. we expect the scene will go for another two days anyway and people should make appropriate plans. again, i want to stress that any information that you have, any videos or photographs that happened, not just at that scene but anywhere in the immediate vicinity, could be helpful to this investigation. our focus is on processing that evidence right now, and we're looking forward to working with our partners to bring the individuals who are responsible for this heinous crime to justice. thank you. >> thank you, commissioner. colonel? >> good morning, i'm the superintendent of the massachusetts state police. as i said earlier in one of our briefings, there's really two or three parts to this investigation. there's the investigative part, which clearly the fbi has taken the lead on, but there's also a logistical and presence

component to this. so i'm speaking to the public chblt you are going to see an enhanced presence from the boston police, from the state police, from the national guard and from our law enforcement partners through the metropolitan boston area over the next days and probably longer. that's not for any particular reason other than to provide some comfort to the public who are using transportation centers or going about their business. so we are engaged with the mbta police in the "t" you will see more troopers, you'll see national guardsmen there, mbta police like you do every day, but that presence will be significantly enhanced. we're doing that for the comfort of the public. we're looking for cooperation from the public. it's not to inconvenience anyone, and we don't think it will. you might also see an enhanced presence at logan airport, no other reason but to seek out

tips or information and kfrlt comfort the public. there has to be hundreds if not thousands of photographs or videos or observations that were made down at that finish line yesterday, and they're sitting out there amongst everyone that's watching this event this morning. i would encourage you to bring forward anything. you may not think it's significant, but it might have some value to this investigation. the mayor has given you tip lines, there are plenty of those, the fbi has them as well. if you call in, i assure you that someone will follow up on your photographs or videos you want to submit for consideration. thank you very much. >> good morning, my name is daniel connelly. i'm the district attorney here in boston. what occurred yesterday in boston was an act of cowardice. while there will be an opportunity in the future at the conclusion of this investigation to officially define this act,

make no mistake an act of cowardice and of this severity cannot be justified or explained. it can only be answered. to that end, some of the finest investigators at the local, state and federal levels have been working through the night to not only conduct interviews and process the scene but to ensure that those interviews are legally sound and that the evidenced is recovered with the greatest care. at the same time, police and other law enforcement agencies have been actively working to ensure the safety of our city. at this point, the loss that we have suffered is enormous, but, thanks to the efforts of emts, police officers, firefighters, volunteers, ordinary citizens and of course doctors, nurses and the medical staff at boston's world-class hospitals, we can say with absolute certainty that more lives were saved. for this we can all give thanks.

in the days and weeks to come, we will do our very best to keep the public and the media apprised and advised of the progress of this investigation and our work. it is important, however, for the sake of the victims and of this city that our investigators be given the room to do their jobs so that the truth can be found and so that justice can be served. moments like this and our response to them define who we are. in the past 24 hours, this city of boston has shown its strength, its compassion, and its determination to see justice done. >> thank you, dan. we're happy to take questions. we're going to try to take as many questions as you have so maybe we'll just go from side to side. yeah? >> what helps to reassure that there will not be more --

>> well, more than the evidence is the extraordinary cooperation among these law enforcement agencies as the mayor and others have said. at the federal, state and local levels and indeed from the region, we have an unpresses dented level of law enforcement support and engagement here and they're working very, very well and very seamlessly with each other under the leadership of the fbi. and that gives me a lot of comfort, should give the public comfort as well. >> anything that helps you understand the level of complexity of the device itself, the level of sophistication or the origin of the materials that would help understand if it's a domestic source or international source? >> let me turn it over to rick who i think is not going to comment. >> thank you, governor. i can't comment on that aspect of that. what i think is important to say and what i'd like to, beon behalf of the boston jttf here

today, there's no known imminent physical threat at any location where we might be conducting investigative activity right now. i want to put that out to the american public, 0 to the citizens of the city of boston and the commonwealth of massachusetts. >> tell us first of all if you know anything about the nature of the device and secondly, can you comment on the fact that there had been a sweep of the area and how is it that two devices this powerful could have alluded that? >> i can't comment on the nature of the device right now. [ inaudible question ] i'm not going to say who it might or might not be in custody right now. >> can you confirm that -- under custody and is looking for has found a second person who is a roommate? >> david, what i can say is i.c.e. is a key component of our boston joint terrorism task force. they are active right now and are interviewing and assisting

us integrally. >> there has been a lot of talk of photos. there was a photo of a man standing on the roof in the background. >> we are processing a lot of digital photographic evidence as several speakers have said including the governor we encourage the continued submission of any graphic evidence that could lead to value. i can't comment on specific tips or leads right now. >> can you tell us about -- >> you said earlier -- >> can you tell us about the surveillance cameras in the area? are you able to use those and how they are helpful and anything about what you are seeing on them? >> karen, i think commissioner davis can probably speak best about surveillance cameras in the area. i think we're processing all the digital photographic evidence we can as quickly as possible with resources from fbi headquarters in quantico. that is a priority of the investigation right now. i'd like commissioner davis to speak about the video cameras. >> thank you, rick. it's a basic investigative

protocol at this point in time for us to secure all of the video this that's in the area. even as we were removing victims yesterday, officers were assigned to go into the local establishments and secure those videos. there are a large number of them so there's a logistics issue right now. we are working with the fbi. they're sending special teams to process that information. it's our intention to go through every frame of every video that we have to determine exactly who was in the area. this is probably one of the most well-photographed areas in the country yesterday. >> as far as people coming and going from the city for work, obviously very difficult to move around copley square. are you asking people to stay away? is that the best recommendation, or do you want people to come and go? >> we want people to come and go. we want you to live your life. we want you to be vigilant. there's no reason to not come into the city. but we do have a threat, and we are working diligently to try to

reduce that threat. we want you to go about your business. give us a little room in the copley square area. be patient with us there as we process this scene. but we are trying to turn it back to the businesses, and to the community as quickly as we can after that evidence is collected. >> you may have 100,000 pictures out there. what do you want people to look for? >> that's a good question actually. what we would like is forwarding any photos that you have around the time of the blast and particularly in that area. but also tell us what time those photos were taken so we don't have to go through the electronic signatures we have some data as to when the photos were taken. naturally photos taken close to the blast, just before, just after, those will be critical and we'll prioritize those. but give us the photos and as much information that can help the investigators move forward. [ inaudible question ]

there's no evidence of that. [ inaudible question ] there is an eod sweep that was done. there were two of them done that morning, one early in the morning and a second one an hour before the first runners came across. those two eod sweeps did not turn up any evidence. but because there is unrestricted access to the race course, simply because it's 28 miles long, people can come and go and bring items in and out. >> commissioner, do you have any evidence that the three people who are confirmed to be dead all thought to be victims, or could one perhaps be the perpetrator or one of the perpetrators? >> they're all victims as far as i know. [ inaudible question ] no. we don't have any information on that. >> could you give us an idea of the breakdown of the impact of the two separate bombs in terms

of casualties, numbers? >> we have a number of 176 casualties that presented at area hospitals. that's including hospitals on the south shore so not just in boston. 176 is the best number i have right now. 17 of those individuals are critical at this point in time, 3 fatalitfatalities. >> in terms of two bombs, though -- [ inaudible question ] >> no one is in custody, right. no one is in custody. >> you said there's an individual responsible for this, does that mean you're ruling out any groups responsible for that? >> no. [ inaudible question ] >> as an ongoing investigation, our investigation will certainly

not be confined very likely to the city limits of boston. it would extend out. it will be a worldwide investigation. we'll go to the ends of the earth to identify the subject or subjects who are responsible for this despicable crime and we will do everything we can to bring them to justice. >> do you know the point in your investigation where you will be receiving any assistance? >> i can't comment on that aspect of the investigation right now. certainly we were using full capacities of the fbi to its fullest worldwide extent. [ inaudible question ] i think the best way i can address that question is what i previously said, that we are interviewing a variety of witnesses right now in a variety of locations and that is ongoing. that is the most i can say about that right now. >> what led you to that address? >> again, that would be commenting on specific leads and investigative activity that

might compromise our investigation so i really can't comment on that. >> was it helpful? did you learn anything from that? anything to advance the investigation? >> i would just say that we are continuing, we have a multitude of resources on the street, the joint terrorism task force, many components of which are with me today, are on the street conducting all logical investigation as quickly as possible. >> so it was part of it? >> i would say we're just -- we are out on the street in a variety of areas both in the city of boston and outside the city of boston conducting an investigation where the leads and evidence take us. [ inaudible question ] i was not aware of any threat information prior to the marathon. >> aware of any sense? >> as i mentioned earlier, i'm not aware of any physical threat information right now from any unexploded devices or any further devices. i'm not aware of any information and to the best of my knowledge there is no imminent physical

threat anywhere associated with this investigation. >> last question. >> -- what would be safe outside the boston area? >> i'd say to the folks watching us that we have a city that's resilient, a city that's working together. law enforcement is working on this issue since it started and we need cooperation from the public. folks out there know that something's going on. give it to the fbi, the boston police, whatever law enforcement you want to give it to you. we're a resilient city. we'll get by this. it's one incident that will not mock the city's history. >> thank you. >> the press conference is

ending now. we got an expected type of debrief from the governor, fbi, district attorney representatives, local law feernsment. headlines for you? the district attorney called it what it is, an act of cowardice. they said that this is an act of an ongoing investigation highly coordinated, that the white house and all federal authorities are stepping up and giving them the resources that they need. there was a new injury number that we've heard, 176, 17 still in the hospital, still with critical injuries. now, that can be a range of things, means that people are still in there fighting for what could be their lives. that's not to overdramatize it. again, almost all of you are not privy to the pictures of injuries that we saw yesterday coming out of those explosions. had you seen them, you would understand why we say that just because somebody is injured and in the hospital doesn't mean that they're out of the woods. that number, 176.

the confirmation that this city is pull together, that the authorities are pulling together, that the resiliency of people who live in boston is being evidenced, something that was pointed out that was not a throw-away statement is that one of the first things that was done here was to take time to recognize the response and the first responders and those who volunteered yesterday. why? well, that's how you survive a situation like this. it can go either way in a moment of crisis. first responders stepping up, volunteers coming in, triaging, nurses there to help with dehydration becoming trauma actors there and taking care of business, helping people survive, stopping loss of life. that's what we saw yesterday. that is the key to surviving an event. the perimeter that's been set, they are trying to collapse the crime scene as quickly as possible. they asked for indulgence on

behalf of media to let investigators do their job. they say it will take several days at least. it's active and ongoing, of course. there was discussion about the risk assessment before the marathon. now, remember, any event like this preceding it, there's a risk assessment done by jttf, the joint terrorism task force. it's done in coordination with local police and authorities to figure out the best way to prepare for anvent. that would have been done here. it is not made public, but it is fairly specific. that's why they say there was no credible threat beforehand. but it also is a window into how they prepare, which leads to the suggestion about, well, how did these bombs get where they were eventually, massive event, sweeps were done. were there gaps? were there opportunities taken? is that a window into what type of information the individual or individuals who did this must have had to do it successfully? those are the types of questions that were raised.

also a lot of assurance given that this investigation is moving forward. they asked the public and media to give all pictures and video that they have. they have hotlines, we'll have them on the web site for you, and as we finish one press conference, we're preparing for another one, am i right in saying that, tell me, control room? we want to go to mass general, the second prong of this story that we're following, the people who are fighting to keep their health in the hospital. press conference right now, let's listen in. >> the intensive care unit, but overall we're very pleased with the results as they are right now. eight patients are in more severe conditions than the rest, and they have undergone major operations, predominantly, unfortunately, amputations because of the devastating effects of the bombs. many of them have severe wounds,

mostly in the lower part of their body,s wounds related to the blast effect of the bomb as well as small metallic fragments that entered their body, pallets, shrapnel, nails that these bombs had. and some had additional injuries we're addressing. again, i'm happy to report at this point that the patients are sick but are in rather stable condition and thank god they're all alive. [ inaudible question ] yes, there are a variety of sharp objects that we found in their body, probably this bomb had multiple metallic fragments in them and we -- we removed

pellets and nails. >> is it something that came from the environment or is it concentrated enough to make you lead you to believe they came from the bomb. >> i believe they came from the bomb but i can't be sure. >> how many amputations have you performed and how many are planned? >> if i have my numbers are right, we have performed four amputations and there are two more limbs that are at risk, but i hope that we will save those l legs. [ inaudible question ] yes, they are in intensive care. they are in critical condition. but at this point we have stabilized their vital signs and their hemodynamic situation is under control. >> what are their injuries, can you describe what has placed them in such critical condition? >> most of the injuries were, again, lower extremity major injuries. from these injuries they bled a lot. we controlled the bleeding

rather rapidly, but certainly they lost a lot of blood and that created d physiologic problems. [ inaudible question ] as far as i know, all of them are americans. >> can you tell us an age range, doctor, of your patients? >> the younger patient so far was 28 years old and older patient was 71 years old. [ inaudible question ] most of the patients that are in the intensive care unit are still intubated and therefore cannot be interviewed. >> what can you tell us about their emotional state and that of their loved ones? >> it's obviously an extremely sad day for all of us, but even more so for the patients and for their relatives. i had the pleasure of interacting with many of the relatives, and obviously they're shattered by the events. we are offering emotional

support and we've pulled all our resources in order to support these patients not only for their disease but also for their emotional status. >> have all of them been identified? >> at this point, they've all been identified. >> doctor, you talk about injuries to the lower extremities. is it unusual to have such a concentration like that to the lower extremities in a blast? >> it's not unusual. this bomb obviously was placed probably low on the ground, and therefore lower extremity injuries are to be expected. >> and there was no internal bleeding? yesterday we heard there might be internal problems. >> there are on a few patients some internal problems that we're still working up. i don't have further information on this one. >> are all patients conscious, or are any unconscious still? >> most of the patients are conscious, but we do have patients who are medically

sedated in order to alleviate the pain at this point and therefore we don't have a full evaluation of their mental status yet. >> doctor, did you screen for biological or radiation issues with these patients? >> it doesn't appear that we have any issue with that at this point. >> you mentioned that there are complications from the blood loss. what are those complications? >> the complications from the blood loss is that the heart made to compensate and multiply their organs in the human body may be driven into failure because of blood loss. but we were very rapid in replacing the lost blood, and i think that for the most part we've saved patients from these problems. >> can you give any sort of estimation -- >> i don't think that any of them were runners. i think they were all spectators. we did treat some runners, but we have not included -- those --

the three patients that i said we received from the marathon were not tramatically injured. one was observed overnight and the other were treated and released. >> has anyone talked to you about what happened? what they saw? >> not to me in the emergency department. george? >> no, we haven't had any more information unfortunately. the teams were extremely busy and concentrating on providing care last night. and we tried to focus on that and do nothing else but that. >> doctor, as the investigators try to conduct their investigation, do they have to clear with you before they speak with patients? >> well, we are always there by the patients and we make sure that they do not suffer unnecessarily at this early point. so we are all in communication to make sure that the patients can talk only when they can really talk. >> can you tell us how many are medically sedated?

>> i believe there must be six or eight at this point. the last time that i saw the patients was about an hour ago, and depending on what has happened to two of them, it's between six and eight. >> what is the prognosis for those six or eight, doctor? >> i think the prognosis will be probably okay. i think that we've stabilized these patients well. they have stopped bleeding. there are still things to be done, but i really hope that the outcome will be more loss of life? >> what is the earliest time you expect -- >> i think the first patients may actually be ready to be released in a few days, but this is too early to predict that. >> have you ever seen anything like this before? >> to that extent, no. >> in terms of severity or quantity? >> in terms of quantity.

>> the four amputations, those are four separate patients, correct? >> yes, correct. >> how is your staff doing? are you well staffed or have you had people come in? >> we were very well staffed, and we were extremely proud of the resources that the hospital placed on this event. quite frankly, it was one of the proudest moments in my life when we went there in the middle of this mayhem i saw endless doctors coming from all over mgh to offer their help in a very, very organized fashion. so we absolutely had no problem with staffing. >> i would also add that the timing -- some of the physicians and nurses work from 7:00 to 3:00 and then 3:00 to 11:00 on the evening shift and of course the day shift all volunteered and said, we'll stay here as long as needed. so that helped us out as well. >> and of the amputees, how many were traumatic amputees versus

amputees from the hospital? >> almost all of them had such severe trauma in their lower extremity that it was beyond salvation so i would consider them almost automatic amputees, just completed what the bomb had done. >> doctor, could you just take a moment to reflect on what the last 24 hours has been like for you, your staff, as a doctor, as a member of this community. what has this experience been like for you? >> the experience is obviously overwhelming. we are all extremely sad. we are suffering emotionally for what happened to the people of boston and many others. at the same time, we can't feel but proud because the medical community here at mass general responded in an amazing way. suffice it to say that some of

the trauma group that happened to be outside the city jumped on planes immediately in order to come back and they did come back within hours. one of our physicians was actually running the marathon and deshydrated as he was, he came back immediately after finishing the marathon to offer his help. yes, these are difficult moments for all of us, but, at the same time, we feel quite proud for what we've been able to offer and extremely appreciative for the opportunity to offer that to the people. >> can you describe the emotional toll? how did it manifest itself with some of your staff? you say overwhelming. i don't mean to exaggerate this, but how did that manifest itself? >> we're all trauma surgeons so we are quite used to seeing unexpected events to a very large scale. so even if we are empathetic and we always stay by the side of

the patient through the physical and the emotional disaster, we all know how to control our feelings and do what's best for the patient and not focus on ourselves. >> doctor, how much do you think having all those first emergency workers on the scene factor into survival rate of the people? >> i think it was an amazing response. as far as i understand, all the -- are not clear. mind you i spent the larger part of the last 15 hours taking care of patients and not learning the details. but i think it was an amazing response and because of the rapid pre-hospital response life was saved. >> doctor, is your team exhausted and able to rest, or do you just keep pushing forward? >> we keep pushing forward. thank god, again, we have endless resources and are able to keep on operating and providing care. >> doctor, this may seem really

obvious, but these extra materials that may have been packed into these bombs, how does that exacerbate the trauma? >> well, after a bomb, there is a number of traumatic injuries. some of them is a direct effect of the bomb when the extremities severely damaged or if there is. but then there is secondary injury from the bomb blast, the wave of the bomb, that can push people away, can throw them and hit them against walls. and there's also another form of injury which is from the particles that are broken and embedded in people. so we've seen all three of them after this event. >> doctor, your colleague at brigham and women's has concluded that all of the --

>> it is i think we're still getting details of all the events that happened, and obviously it's very difficult to conclude based on initial impressions. i wouldn't exclude completely the possibility that some of these fragments are environmental, but my opinion is that most of them were in the bomb. >> doctor, what is the security like in there? are there guards watching the patients? >> so the moment the intensive care units have restricted access. there is increased security around all the hospitals in the city, and you can see some of the police around this campus. that is a precautionary measure. my understanding is that all of the major hospitals are take -- have been given the same protection. >> doctor, getting back to your previous answer, you said it's

your opinion that there was extra material. how do you reach that? what's the tip-off? >> because of the consistency of the fragments. most of them are pellets, some of them are nail-like, so i think it's unlikely they would be so consistent if they were pulled up from the environment. [ inaudible question ] >> nails yes, or sharp objects. i can't say what they are with certainty, but that's what they looked like. >> do you know how many you took out? >> they are numerous. numerous. there are people with 10, 20, 30, 40 of them in their body. or more. [ inaudible question ] we have -- we're close -- we're working very closely with investigators and handed them whatever evidence we can find. >> what are you seeing in terms

of resiliency from the patients? >> i think that the patients responded really, really well. the patients that were able to talk when they first arrived and they were not immediately sedated and intubated for the purpose of an operation were amazingly resilient, were really pulling it together and quite frankly because of the patients our life was made easier and we were able to provide better care. the patients were really amazing. >> can you be more specific about that? give us some specifics? >> most of the patients were calm. they were responding to our questions. they allowed us to examine them from top to bottom in detail. and when we had time to explain our decisions and the course of care that we intended to take, the patients agreed.

it was a very, very calm and collective response by the patients. >> i know you can't be sure, but would you say that none of your patients are in danger of dying? >> yes, it is too early to decide that, but at this point i'm extremely happy with how things are going. >> doctor, how do you tell someone that you may have to take their leg? >> it is a devastating thing. it is extremely difficult to come to this. but, mind you, these patients who had amputations were the most severely injured ones and, therefore, quite frankly these were the ones that were immediately intubated, immediately rolled into the operating room, and there was no real time to have a lengthy discussion. the focus was on saving their life from bleeding. [ inaudible question ]

as far as i know, we don't have any patient at mgh that is related to each other. i don't know whether there are relatives of them that are trfed to other hospitals in boston. >> and that is the case. we have patients here who have relatives that have been admitted to other boston hospitals. >> when are you planning another update? >> as we get more information. there's not a set time right now, but as we get more information. >> doctor, could you say your name and spell it? >> velmahos. >> thank you, doctor. >> chief of trauma surgery at mass general. >> thank you, doctor. >> thank you. thank you very much. >> is any of the family members feel like they'd like to speak? >> so we're coming out of this press conference now at mass general.

a lot of information to pull out here for you. two developing aspects to this story, the investigation. we just heard that press conference. now the people who are still fighting for their lives, and that is not an exaggeration as we've been saying to you all along. 176 casualties that number of injuries increased, confirmed by the doctors at mass general. 17 critical still. now, what does that mean? it can mean a lot of different things. we know that people are sedated because of their pain so that their mental injuries are not now known. there's an unknown factor in that. that with such tremendous blood losses there is fear of organ failure. they have done what they can to minimize that exposure, but it's unsure when asked if whether or not he could say that no one else is in threat of dying, the doctor said it's too soon to tell. he feels good about what they've done, that they've done everything they can. nobody wants to overdramatize this situation. it benefits for no hype for

sure. but remember the urgency, people are still fighting. many families had more than one person affected by this. some are in different hospitals. imagine the strain on a family trying to figure out who is in which hospital, what the nature of the injuries are. something else that came out that's interesting, the doctor who has experience with explosives says that he believes that the shrapnel injuries he's seen were not merely frak, things picked up from surrounding areas and put into bodies. he believes they were in the bomb itself. why? he's seeing 10, 20, 30, 40 particulate matter that he believes were in the bomb. he also says something that we have could keep close care on here, that these trauma centers, as great as they are, have never seen anything like this in volume or severity. he also said he's never seen a response like this either, that it amazed him how the teams came together, with exhaustion. he told the story of a physician who finished the race, went into the hospital to save lives.

that's the kind of dedication and resilience that mattered on the ground yesterday and should define the boston marathon and these bombings and attacks for us going forward. there is more information to be had. when we come back after the braeblg, we just heard the injuries described, the current bamt battles. we'll talk to someone who lived through the explosion, was knocked down but lived to tell the story, will tell us what it was like to be on the scene, when we come back. the humble back seat.

welcome to the cnn audience in the country and everywhere else. i'm chris cuomo here in boston. we are monitoring the attacks at the boston marathon. we just had press conferences where the officials requested more video and pictures from anybody. they need it, want it, go to the cnn web site, we'll put up help lines for tips and any videos that you can offer. also just came off a press conference at the hospital where we learned that people are still fighting, may still be at risk for their lives there. the situation is far from over. we go from the injuries that are being dealt with sto the people who witnessed them and lived through it. i'm here with pamela brown. pam, you've been here the whole time reporting it out.

what have you heard from people who made it through and tell the story now? >> well, chris, we just spoke to a witness whose name is michael murphy. he was visiting from canada watching his son in the marathon. yesterday he was right across the street from where the second explosion happened. he said he witnessed so many horrific things, but what has left an indelible mark, the image that stayed with him was a little boy he saw on the ground right after that second explosion, after hearing reports of the death of 8-year-old martin richard, he believed that little boy that he saw may have been him. >> when you're in such shock, you don't know really what you're seeing, and i thought i saw a child laying to the left. my wife didn't see that, as she later told me and i thought perhaps it was clothing or someone's limb because there was a man there missing a limb. but it was surreal, and whoever did it was just the embodiment of evil.

it's unbelievable. >> and you said the bombs were on the ground rather than being -- >> there's no question those bombs were in knapsacks or something on the ground because the woman whose clothing was melting into her skin, it was on her legs. the man lost a leg. if that was the child, the child was small. we would have been hit 50 feet away across the street if the bombs were higher. the bomb to the right, 75 yards away, nobody really knew what it was. everybody kind of kept going on for a few seconds. but the one in front of us at starbucks, when that happened there was no doubt, within a second, everybody was running and screaming. >> what was going through your mind in that moment? >> we didn't know how many bombs there were. i thought perhaps there were more bombs because there had been two and i was afraid there may be some on our side. i wanted to get my wife out of there. she wanted to get down into the street because timothy, our son,

was due, as we thought, to cross at that time. we didn't know if there were other bombs up the street. we finally got ahold of him two hours later, but we were so excited to be here at the marathon to see our son run, and it's a war zone. >> is there anything that sort of surprised you? you said you were in such shock you kind of had a different reaction than you might suspect you would in a situation like this. >> i didn't think that i would be calm. and i wasn't calm, i was just in complete shock. when you see bodies around you and limbs, you think in advance that you're going to be just -- you'll melt down, but you really -- you're thinking, trying to move people out of there. and i tried to get my wife out of there, but i suppose to her credit she immediately wanted to go down into the street. but you're caught in a dilemma because you know it's terrorism, you're wondering if there's a

third bomb to take out first responders and people that are helping, but this was designed to maim and kill, and it did. >> what's interesting, chris, he also said going through the experience yesterday brought back memories of 9/11. he says public sporting events, large public gatherings will never be the same, just as air travel hasn't been the same since 9/11. >> reporter: you can see the confusion just in one family, what do we do, where's our son, should we stay, should we go. >> that's what's so interesting here. he said, you think maybe you'll act a certain way when you're in a situation like that, but his wife's first instinct was, i want to go find my son. and he was trying to pull her back but realized later that was probably the right thing to do. >> it's interesting how many people dealt with it in terms of, oh, maybe it's a celebration and that confusion kept them calm. those that knew exactly what it

was and kept their poise. thanks, pam. we'll hear stories like this for a long time and they help in shaping what happened. we'll go to tina husted, the wife of the secretary of state of ohio, also a runner here in the boston marathon. remember it's not just about boston. just about every state is represented, about 100 countries, certainly ohio. tina, thank you for joining us. you're running the race, you're tired, you're about to finish. what happens? >> well, you know, if you've never run a marathon, you just -- you're just completely exhausted. you've put every ounce of energy into this. fortunately i was done, i had been done for a few hours, but we were waiting in a van about a block away for some other runners that were in our group, and we were sitting there. all of a sudden we heard had this incredibly loud boom and i said to the lady sitting next to me, that sounded like a bomb.

she said, yeah, it sure did. so we waited for a bit and probably two or three minutes later, you know, mass chaos ensued and people started running from the scene. then all of the ems trucks and vans and vehicles started flooding the area. it was a big traffic jam and obviously people were just very nervous and worried about what was going on. we didn't realize it was a bomb initially until we were able to confirm that with some other people. >> reporter: you make an important point, a distinction that matters here, tina. you have different types of runners in this race. you're what they call an elite runner. you finish early on. this happened at the 4:09 mark. you're done. you have very different experiences, people out there in their own world of mental and physical exhaustion, then you who is decompressing, yet you're kind of pinned in, right? your options of what to do and where to go not easy right then, were they? >> no, they weren't.

and my immediate thought was obviously for the people that were close to the site. and if you've never been to the boston marathon, it is -- there are a lot of people in a very small, confined area, and fortunately my family was not there. my immediate thought was, i want to get away from here because, as your previous person had mentioned, you're worried that there are other bombs in the area. you just want to get away and get back to your family and get to safety. >> reporter: what did you see in terms of the response of people around to help those who were in need? really seems to set this incident apart. >> well, one of the best parts about this as you've heard many times is the medical support at that race is incredible. i mean, as soon as you finish the race there's a very large medical tent.

many stops along the race as well. as a matter of fact, when i finished, i was having a difficult time walking, was a little dehydrated, and i actually utilized one of the ems golf carts. i was thinking to myself, boy, these people probably are pretty bored today because there wasn't a lot of activity when i was with them. i'm sure they felt much differently a couple of hours later. >> reporter: tina, thank you so much. i'm happy that you got to finish the race. so many did not. you're home now, right? your family knows you're safe. you know they're safe. >> yes. >> reporter: thank you for sharing your story with us, and we wish you well going forward. >> sure. thank you. >> reporter: tina husted from ohio, the wife of the secretary of state. she finished the race earlier. remember, this happened at 4:09, 4 hours 9 minutes in. that's when the widest swath of

run runners, the regular runners, are going to be coming through. did this person know that, whoever planted this bomb? was this the right place, one of the most congested corners? these are questions fueling the investigation. when we come back, new information about the people that the investigation is focused on right now. are they suspects? no. but they're certainly the focus. we'll find out when we come back. ♪ [ female announcer ] from meeting customer needs... to meeting patient needs... ♪ wireless is limitless. ♪ from finding the best way... ♪ to finding the best catch... ♪ wireless is limitless.

>> reporter: you're looking at two screens right now, on the left the white house where the flag is being put to half mast, obviously in solemn remembrance of those who were lost and injured here in boston, the attacks during the marathon. on your right, an ongoing presser at brigham and women's hospital where there are still people in critical condition fighting for their lives. let's listen in. >> really cooperative with the provider teams to really help us to take care of them. amazing in how they handled the initial pain in the few minutes it took us to get that pain treated properly so they were comfortable. and i would say in terms of recollection their recollection starts at the moment of the blast. they could tell you where they were but then there's this event and everything after that. it was, for most of these patients, something that no

human being could possibly be prepared for, and there was i think a tremendous amount of confusion in the area immediately after the blast. [ inaudible question ] you know, i've never, ever been surprised by patients' resiliency. i think more people are challenged the more they rise. i've seen many patients with critical illness and critical injuries and still after 30 years of doing this i'm still impressed with how they handle it. [ inaudible question ] they are about half and half male and female, the youngest patient 16 years old and oldest 62. [ inaudible question ] so characterizing these patients as critical means that they are still in a state where their health is in balance. so we will -- when we consider them stable we'll move them down

from critical. we would count these patients as critical patients. [ inaudible question ] all of the amputations -- the one amputation has occurred and the two patients with threatened limbs are here at brigham and women's hospital and our falkner hospital site, none of those patients were amputated. [ inaudible question ] so it's really -- the presence of these projectiles from the blast really a proximity issue, the closer they are to the source the more likely they are to get hit with one of these. from a patient's perspective, it really doesn't make any difference. they're injured by the blast impact itself, and some of them have foreign bodies that were sent in that were things lying around on the street and others

have foreign bodies that were part of the device. but all of those foreign bodies can be removed and they have the potential sometimes to damage blood vessels or damage nerves. we have one patient who had a pellet go through an artery, and that artery had to be tied off. but, in general, the patients wouldn't feel any different if they did or did not have the shrapnel in them. [ inaudible question ] i think erin can take that one. >> so the presence of law enforcement is really at the request of boston police department. we have our colleagues at the other area hospitals that have received our patients, it's our understanding that there are armed law enforcement agents out of an aabundance of caution and we're happy to have them as long as they want to stay.

[ inaudible question ] we're told there's no perceived threat at any of the institutions. it's just precautionary at this point. thank you. [ inaudible question sfxt [ [ inaudible question ] >> so some from the shrapnel perspective, some of the shrapnel injuries are actually pretty minor. there are pieces of metal embedded just under the skin, not near anything important. so those patients really that piece of their care is quite simple. the patients who had sort of the non-shrapnel related injuries predominantly have fractures and have areas of their muscle and skin that has been destroyed or removed by the blast. so it's a matter for surgeons to salvage that area and do reconstructive surgery. [ inaudible question ]

we had 31 patients here at brigham and women's hospital of which 15 were admitted an ted a went to the operating room, 5 of them are in critical condition. at brigham and women's falkner hospital, we had a total of 13 patients, 4 of whom went to the operating room and 1 of whom is critical. [ inaudible question ] so we don't improvise when these kinds of things happen. we've drilled this a lot. we know how to do this. we have a standardized definition system that allows us to specify the level of response we need, and it goes out in an automated way to the people who should hear that message. and it tells them of the level of the ramp-up that we're doing and they know from that where they should report. so yesterday, because it was during the day, we had

additional staff on in any case because of the boston marathon, because we always get more patients,s not this kind of patient but always more patients marathon day. so we had additional staff anyway. and because it was daytime when we ramped up, we had virtually the entire trauma surgical service in the emergency department working with us within minutes. >> reporter: lost him. we're no longer hearing that press conference. that was brigham and women's hospital. but we got the headline from it. i'm here with john berman. this is the cnn way, we keep passing it off one to another, keep the team coverage going. some of the headlines here that went on before you came back in was that they do believe that there were some foreign bodies that were exploded out of the device. early on ballistics and explosives guys were saying they didn't think these bombs were

kpai capable of that. >> two doctors are saying at the hospitals that the scope of injuries they're seeing and literally the things they're pulling out of people indicate not just pieces from fences or trash cans that may be nearby, debris, but things that were inside the devices themselves. we're hearing that now from two sets of doctors at two different hospitals. >> and a major headline because there is sometimes in these situations somewhat of a tendency of certain media to extend, expand, keep the story going. here from the doctors themselves who have every interest in mitigating the danger, they can't say that people are out of the woods yet, we're saying this because we want you to nour understand it's not over, people's lives are in the balance because of how serious the injuries are. >> and the number is growing in terms of the number of people injured right now. the number i believe we have now is 176. that may just be because we're getting more current, better information. but not just the number is growing but the number of people in serio or critical condition is also growing. they are watching them very, very carefully. the care they are getting at

this time, some 20 hours after this event, is still crucial. >> people sedated because of pain. they don't know what's going on where their minds yet. but we know this for sure, john, and we're reporting the triage, response on the ground made all the difference in terms of surviving this situation. >> they saved lives, no question. i talked to a doctor on the scene who said at one point there was four doctors to every patient on the ground. >> that's the coverage for now. we'll go to break now. more on the investigation, j.b. will pick it up when we come back.
